To all whom it may unico n lie it known that l, Cninanrs ll. 'lornamwok, ('illZtll oi" the United States. and resi dent of Syracuse. in the want at 011011 daga and State o't' New York, have invented vertain new and useful lniprn't'tanents in lype-\Vriting liilauhines, of wnich the following if; a aperitication.

My invention relates to typewriting ina- ('lll'lltS and it has for its rhieipal object to provide an improved, ninth tor for such mat-limes.

The

A spare lmrorkoy it) ismonnted on a stem 27 wlnuh extends downward through a frame plate 13 which is similar to the frame plates :30 near its rear end. stands in position to engage a pin :11, \\'l!i('ll projects from the front. tare ot' the gate It! The construction is such that: it the space key or bar bedepressed the universal liar will be operated in the Same manner as i one of the carriage keys. The space key 26 is elongated, as Shown in Fig. 8, and extends part way across the keyboard in front of the keys: 16. -ln order to better sup port and stvarly this elongated key an arm Ll-Ll is pivoted. to the slot 1 27 at 235 some dislance above the arm Said arm St is pivoted on a shoult'lerrd and headed screw 36 which is threaded into the frame plate 28. To give the arm a better hearing on the sci-m, 51G,- Silitl arm is bent in the form indi cated in Figs. 1 and 3 so that it bears on the mounted in a slot, the walls of which prevent .the under side thereof.

end thereof an escapement wheel 44 which the head 25 of the shaft 24. Said feed dogs screw 36 at two points.

'A feed rack 37 is mounted on the rear edge of the carriage and has rack teeth on Said rack teeth mesh with a pinion 38 which is journaled on a stud projecting from an arm 39 which in mm. projects from a sleeve 40 which surrounds a shaft 41, which is journaled in a housing 4201; the top plate 4. The shaft 41 has fixed on the forward end thereof a pinion 43 which meshes with the pinion 38, and said shaft has rigidly mountedion the rear coperates with the feed dogs mounted on may be arranged for either the ordinary or reverse feed, but inthe present case. dogs adapted for the ordinary feed are shown. A stepping dog 45 is pivoted on a pin 46 which is supported in ears 47 rising from the head 2-5. This dog is normally enga ed by the escapement wheel 44, as shown in *i s. 4 and 8. A holding dog 48 is mounted be ow the steppin dog 45 and, as best shown in Fig. 7, sai do is pivoted on a vertical pivot consisting o a shouldered and headed screw 49. Lying as this dog does between the two ears 47, it is substantially rotation of the dog about its pivot in one direction, but said dog has a notch 50 (Fig. 7) in one side thereof and is cut away on the other side and .a spring 51 is compressed between the dog and one of the ears 47. In the ordinary operation of the machine this spring holds the do in the position shown in Fig. 7 so that the og 48 ordinarily acts as a fixed dog.

lee

to engage the next succeeding tooth of the escapenlent wheel when the key is released. In this operation the holding dog 48. is pushed under the tooth of the escapement wheel by the spring 51.

My tabrilator mechanism comprises a tabulator bar 55 which is mounted on arms 56 which are secured to the carriage 6 by screws 57 or in any suitable manner. The arms 56 extend upward and backward from their point of connection with the carriage, as shown in Fig. 1. The tabulator bar 55 is or may be of rectangular cross section and is formed on its upper and lower sides with a series of notches or transverse grooves 58 spaced apart a distance equal'to the letter space feed movement of the carriage. One or more stops 59 are mounted on the bar 55. As shown in the present case, these stops are made of sheet metal having an open ended slot which fits over the tabulator bar 55 in one of the pairs of notches 58.

The denominational stops are disposed beneath the bar 55 and consist of the upper ends 60 of a series of vertically movable bars 61 which are pivoted at their lower ends at 62 to the rear ends of a series of levers which extend from front, to back of the machine, beneath the rock shafts 11 and 30 and which are pivoted on a stationary frame rod (34, which is supported at its ends in the side plates 1 of the main frame. The vertically movable bars-61 come up behind the top plates 4, as shown in Figs. 1 and 9, and above said top plate they areloo curved toward the front of the machine and/ the stop portions 60 of said bars extend slightly upward from said forwardly extending portions. The upper ends of these The carriage is drawn across the machine f fi IQSt in 510% formed in an upward by a strap 52 which is connected at one end tension of the housing 42 and are spaced to a pin 53 depending from the carriage and apart a letter space distance. Above the. t th th d t th usual i d 54 back plate 2 ofthe machine frame, the bars Th mechanism th f degcrlbed i 61 are curved as shown in Fig. 1 so that the y b sub t ti ll lik th t di il lower cnds'of said bars lie in front of said used inthe Smith Premier machine, with frame plate 2. The rock shaftsll are arthe exce tion /of the construction "10f the ranged in verti cal ticrs,.and there is a Wide holding 0g 48 and t e mechanism is adaptspace near the middle of the machine be ed to be used in the ordinary way for ,writ-' tween two of these tiers. The bars 61 utilize ing and feeding the carriage. The ordinary this space, two of them being bent oil as operation of the feed dogs is shown in Figs. shown in Fig. 3, to avoid interference with 4 and 5, the former of which represents the the rock shaft 30. The levers 63,..are not parts in the position they occupy normally parallel, but fan out, toward the front of and the latter in the position they occupy the machine, so that their forward ends when one of the character keys or the space are a suitable distance apart. These for- 1 0 key is depressed. As shown in Fig. 4, the Ward ends of the levers (33 extend upward, stepping dog 45 is normally engaged by a as shown at 66, bclng guided by slots formed tooth o the escapement wheel 44 but when in the forward one of the frame plates 12, the space key or one of the character keysis as indicated in Fig. 1. These upward exdepressed the gate 19 is moved to the right tensions 66 of the levers 63 are bent off to and the shaft 24 and its head 25 are swung form lugs or cars 67 which stand just back to the osition shown in Fig.- 5 when the of the space key or bar 26.
